Jack Barton on Grantchester (2020)

Jack Barton guest starred on this week's new episode of the UK series Grantchester. Episode 4 of the fifth season opened with Jack's character, Chris Hartley running naked through the streets. He crosses paths with several surprised residents and runs right through leading men Geordie & Will. While detective Geordie wanted to go after the young man, the vicar Will urged him to let it go, chalking it up to youthful antics. Unfortunately, the next day, the duo responded to a call leading them to the young man's dead naked body in a field, presenting them with their case for the week.
